A brief word on the other applications. A substantial amount of research has been done regarding Carroll aspects of gravity [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. Carroll fluids have been addressed in [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}. New links have emerged between Carroll symmetry and cosmology and dark energy [14]}, as well as connections to condensed matter physics through the theory of fractons [15]}.
